Droplet transfer behavior of narrow gap laser wire filling welding

International Journal of Modern Physics B, 2019
In this paper, we study the droplet transition behavior of narrow gap laser wire filling welding under the condition of changing welding speed and wire feeding speed, and it was observed by high-speed photography.

Transfer of heterogeneous droplets in the field of a temperature gradient

Journal of Engineering Physics and Thermophysics, 1993
The thermophoresis of a double-layer moderately large volatile droplet with a solid core, placed in a binary viscous gas mixture, is considered The thermodiffusion within the volume of a two-component gas mixture is allowed for, and all corrections for the Knudsen number are taken into, account completely.

Pulsation and Mass Transfer of Pendent Liquid Droplets [PDF]

Nature, 1955
Lewis and Pratt1 observed that pendent drops containing solute which diffuses into the surrounding continuous phase sometimes showed ripples and pulsations at the interface; this was associated with increased rates of mass transfer. We have observed similar behaviour with pendent drops of nitrobenzene, chlorobenzene, carbon tetrachloride and chloroform

Flow and Heat Transfer in Droplets-Film Interactions

ASME 2019 Heat Transfer Summer Conference, 2019
Abstract Multi-droplet impact on a thin liquid film covering a heated wall is numerically studied using a three-dimensional model with an implement of a random disturbance subjected to Gaussian distribution. The model can effectively simulate the splashing process after droplets impingement.

The Effects of Impurities and Solutes upon the Charge Transfer of Droplets

Environmental Letters, 1971
Abstract The rates of charge transfer of evaporating droplets of radius less than 5 microns have been measured by means of a Millikan Oil Drop apparatus. As the evaporation proceeds, droplets of pure liquids seem to retain their charge at a near constant level, but droplets of liquid dispersions containing some immiscible substances steadily loose ...

Spontaneous transfer of droplets across microfluidic laminar interfaces

Lab on a Chip, 2016
Passive transfer of droplets across the laminar interfaces of two immiscible fluids is successfully achieved by precise control of the interfacial energies in a three phase microfluidic system.
